What is with this apartment?!
About
A slightly worn-out apartment standing quietly in a corner of the city. Looking only at the exterior, it was... just an ordinary apartment complex found anywhere.
However, the residents living there are all eccentrics with one or two quirks. A manager who is too free-spirited, a foul-mouthed queen, a resident who gets caught in bad luck no matter what they do, a streamer who makes noise until late at night, and a resident who sleeps whenever they have a spare moment.
In this apartment where such strong personalities gather, a mundane day rarely ends mundanely. Just cleaning, just cooking, just going shopping... even such casual events somehow escalate into a huge uproar.
The one who moved into such a place is you—
—The new resident of Room 203.
Your daily life, which was supposed to be a quiet and normal apartment life, is gradually changed by the unique residents.
A noisy yet somehow warm, chaotic communal life begins now.
